I feel like that could create a balance issue with the bandit, her magic is so cheap that spamming acumen and healing magic cyclically could reduce the actual strategic aspect of the fights. Probably not a big deal though, the bigger question is how the hell SP transfer between encounters is supposed to work. its utterly beyond me.
In the starting area I could see that simplifying a few encounters. But it's also burning two actions for a single heal that probably won't be able to keep up with bigger hits instead of pumping out your own damage, so the trade off may or may not be worth it (especially as fights get more difficult).
As for TP, I actually don't know how it's meant to transfer between battles. That's an Rpgmv thing I need to look more in to.
the thing about taking hits that you can barely survive is that if you heal you are essentially farming TP with minimal to no significant HP loss over the time frame while having biblical TP reserves that you can use to trash the encounter. It's a very specific relationship between one character and one merc but it will still be something I keep my eye on for the next build. speaking of, would that be in April?
